GENERAL CHARACTERSTICS OF MADREPORA OR ACROPORA​

  • Commonly called as Horn coral. 
  • It plays important role in coral-reef formation. 
  • Colony branched, being either flagellate radiate or thick. Branching less towards the periphery. Colony is partly porous or reticulate covered by perisarc. 
  • Colony consists of cylindrical cups or corallites for polyps in coenosarc. 
  • The corallite is secreted by basal discs of polyps and is composed of calcium carbonate. 
  • Polyps look like flowers. Terminal and lateral polyps possess 6 and 12 tentacles respectively, and are without central columella. 
  • Internally mesenteries are bilaterally arranged and coenosarc contains a network of canals. 
  • Sometimes small crustaceans are found in association with horn corals.
